Application filed. January 10, 1914. Serial No. 811,405.

To all whom it or 11 concern Be it known that I, C-nu'ncxcn A; Hon-1n, a citizen of the United States, residing at- Morrillton, in the county of Conway and State of Arkansas, have invented. certain new and useful Improvements in (otton- Seed Separators and Cleaners, of which the following is a specificatiom reference being had to the accompanying drawings. Y

This invention comprehends certain new and useful in'iprovements in cotton seed separators and has for its primary object to provide a device of this character which may be incorporated in a cotton seed conveyer tube for the purpose of separating nails and other foreign matter from the cotton seeds as they pass through the conveyor.

Another object is to provide a device of this character wl'iich will be extremely sim ple in construction and operation and in which will be included a separator box formed of t'oraminous material and through which the seeds are forced, thereby separating the same from nails and other heavy foreign matter and allowing said foreign matter to escape through a suitable discharge pipe.

it further object is to generally improve and simplify-the construction and operation of devices of this character and provide the same with a cut off valve, whereby operation of the device may be dispensed with, when desired.

\Vith the above and other objects in view, my inventirm consists in certain'novel constructions. combinations. and arrangements of parts to be hereinafter more fully described, claimed, and illustrated in the acco nmanying drawings, in which-- Figure 1 is allongttudinal sectional view througlrnzy *cth npleto device: and Fig. 2 is a transverse sectional view on the line 2-2 of Fig. 1 looking in the direction indicated by the arrow.

Referring more specifically to the.draw ings in which similar reference characters designate corresponding parts'tln'oughout the several views, 1 designates the conveyor tube leading from the milh not shown, to the delinter, also not shown, and having positioned therein, the conveyor screw 2.

It is a well known fact that nails and other foreign matter may be frequently 'found mixed with cotton seed as the latter leave the mill, and I have therefore provided my improved and novel separating is secured upon the conveyor tube 1 above this open upper portion. Within the casing 3 is a separator box l which may be formed of wire mesh or any suitable fm'aminmi.-: material and which has an open bottom.

The casing has an inclined upper wall and i an exhaust flue 5 projects upwardly from the upper edge of said upper wall through which the air employed for blowing the seeds through the separator box to tilill'2llt the seed from the foreign matter may escape. An adjustable deflector plate i hinged at its upper end to the inner face oi the upper inclined wall of the casing' l. above the upper forward corner of the separator box t to deflect the seed blown through said separator box and cause Said seed to drop upon the forward portion of the conveyer screw 2 to be conveyed to the delintcr. The deflector plate (3 may be readily adjusted to the desired angle by means of the lever 7 which is extended through the opening 8 in the forward wall of the casing 3 and has the teeth 5) formed along its longitudinal lower edge for engagement with the lower wall of the opening 8. the inner end of said lever being pivoted to the upper face of the deflector plate 6.

The portion of the -conve ver tube 1 is also open beneath that portion of the conveyer screw 2 covered by said casing 3 and the air conducting tube 10 has one flared cud secured to the lower portion of the conveyor tube 1 around this open portion of the same. This tube has a blower fan 11 positioned therein which .-erves to force air through said air conducting tube 10, through the conveyer tube 1 w'vitzhin which the screw is {insitioned, through the scparatt ir box t and-the casing 3, and out of the latter by w v o f the exhaust 'tlue 5, th* air serving offer-(e the secd from the conveyor screw through the separator box 4 and against the dellector plate G, by means of which the are again detlectcd to the convever screw? to.be conveyed to the didintcr, the foreign matter dropping from the conveyer screw into the aim-miducting tube 10 and traveling downwardly in the samc along the forward portion thereof, until said foreign matter reaches the discharge pipe 12, through which itis I under face of the conveyor tube 1. It will.

conveyed to any suitable point. It will be undcrs iod that portion of the air con-5 ducting tube connected with the conveyor tube 1 inclined and that the foreign matter disch pipe 12 has one end secured in the lower wall of said air conducting tube 10.

A valve plate 13 is positioned in the air conducting tube 10 and has its lower edge hinged to said air conducting tube 10, at the lower wall of the opening within which the upper end of the -ioreign matter discharge pipe 12 is secured in said air conducting tube. The valve plate 13 may be readily adjusted by the lever 1a which has its inner end pivoted to said valve plate 13 and which projects through an opening in the lower inclined wall of the air conducting tube 10, said lever being provided along one longitudinal edge with the teeth'15 for engagement with one edge of the opening through which said lever ext-ends. The valve plate 13 serves to prevent foreign matter "from passing over the upper end of the foreign matter discharge pipe 1-2 and also serves to direct the air from theblower fan 11 to the upper inclined portipn of the air conducting tube 10 and away from the foreign matter descending to the foreign matter discharge pipe 12.

When it is desired to dispense with the use of the separator, oper lion of the same may be prevented by simply sliding the slide valve 16 to position over the upper end of the air conducting tube lO by lever 17 which has one end connected with the forward ed e of the slide valve 16 and t:

is provided with an. elongated longitudinal slot 18 through which the pivot pin 19 is positioned, said pivot pin 19 extending transversely through the bottom of the slide valve supporting casing 20 secured to the also be understood that the slide valve 16 is slidably engaged against the outer face of the bottom of the conveyer tube 1 and slides through an opening in the front wall of the air conducting tube 10, 'at the upper end of the latter and .vhe'n in its operative position, closes the upper end of said air conducting tube 10, thereby pre enting the blower fan 11 from reaching the conveyer tube 1. .lt will be clearly apparent that when the slide valve 16' is in its forward or inoperative position, the cotton seed will travel through the conveyor tube 1 without being forced through the separator box a.

From the toregoin g, it will be clearly ap parent that I have provided a cot-ton seed separator which is extremely simple in con;- struction and operation and cheap to manunieans ot the l facture as well as highly ellicient and efiective in use, and one which may be readily incorporated in a conveyor tube without changing the construction of the same.

VVhile' I have shown the preferred embodiment of my invention, it will be understood that minor changes in the details of construction and arrangement of parts may be made within the scope of the appended claims without departing from the spirit of my inv'ention or sacrificing any of the advantages of the same.

Vlzat I claim is 1- 1. A device of the. classldescribed com-- prising a casing, a separator box positioned in saidcasing, an air exhaust flue carried by said casing, a conveyor tube, an air conducting tube, said casingand separator box being positioned upon said conveyor tube, said airconducting tube being connected with the conveyor tube, said conveyer tube having communication with the separator box and the air conducting tube, means for forcing air through said air conducting tube to force materials from the conveyor tube through the separator bOX to separate said materials, a discharge pipe extending from. the air conductin tube, a deflector plate disposed in the air conducting tube adjacent the outere'dge of the mouth thereof.

2. A device of the class described com prising the combination, with a conveyor tube and air conducting tube connected therewith, of a casing, a foraminous sepaand air conducting tube having with one another, said conhaving COIHIHUIUCH veyer tube l communication veyer tube and. casing tion with one another, an air exhaustflue carried by said casing, a blower positioned in said air conducting tube to force material from the conveyor tube through the separator box to separate foreign matter from said material, a deflector member within the casing for deflecting the material. and causing the same to return to the conveyer tube after passing through the separator box, a discharge pipe for the foreign matter carried by the air conducting tube, means for preventing the foreign matter from reaching the blower, and means for cutting I of? communication between the air conducting tube and the conveyor tube.
